Convert cell array with different datatypes to numeric

Hi everybody,
I am dealing with a cell array, where single numbers are saved as strings in the cells and some cells are empty. So cell2mat does not work. I want to convert the vector to double while keeping the numbers and replacing the empty cells with NaN.
What would be the fastest way to do this?

As you only have "single numbers" in the cells, then you can use str2double directly on the cell array:
>> A = {'123',[],'4','5678',[],'90'};
>> str2double(A)
ans = [123,NaN,4,5678,NaN,90]
The documentation states: "If str does not represent a valid scalar value, str2double returns NaN."

Thanks, I get the following error using str2num:
Error using str2num (line 32) Requires string or character array input.
However, I dont know why...
My answer uses str2double, not str2num.
